[0056] Next, reference is made to Figures 1 - 15 Describe a cooking appliance 100 according to an embodiment of the present invention. The cooking appliance here may be a pressure cooker, a rice cooker or a slow cooker, etc.

[0057] As Figures 1 - 15 shown, the cooking appliance 100 according to an embodiment of the present invention includes: a pot body assembly 10, a lid assembly 20 and a driving device 30.

[0058] The pot body assembly 10 includes a pot body 12 and a first locking member 11. The pot body 12 has an opening at the top. The first locking member 11 is provided on the pot body 12. The first locking member 11 is arranged around the opening at the top of the pot body 12. The lid assembly 20 is provided on the pot body assembly 10.

[0059] The cover assembly 20 is movable relative to the pot body assembly 10. The cover assembly 20 is used to open and close the top opening of the pot body 12. The cover assembly 20 includes a cover body 21 and a second locking member 22. The second locking member 22 is provided on the cover body 21 and is arranged around the cover body 21.

[0060] When the second locking member 22 and the first locking member 11 are engaged, the cover body 21 can be locked to the pot body 12. When the first locking member 11 and the second locking member 22 are disengaged, the cover body 21 can be unlocked, so that the cover body 21 can be opened.

[0061] The driving device 30 can drive the first locking member 11 or the second locking member 22 to rotate, so that the pot body 12 and the cover body 21 can be switched between the locked state and the unlocked state. When the pot body 12 and the cover body 21 are in the locked state, the first locking member 11 and the second locking member 22 are engaged. When the pot body 12 and the cover body 21 are in the unlocked state, the first locking member 11 and the second locking member 22 are disengaged. Furthermore, by driving the first locking member 11 or the second locking member 22 to rotate, the driving device 30 can lock or unlock the cover body 21, which can simplify the driving mechanism for locking or unlocking the cover body 21 and improve the reliability of locking or unlocking the cover body 21.

[0062] For the cooking appliance 100 according to an embodiment of the present invention, by providing the first locking member 11 on the pot body 12, providing the second locking member 22 on the cover body 21, and the driving device 30 can drive the first locking member 11 or the second locking member 22 to rotate, so that the driving device 30 can drive the first locking member 11 and the second locking member 22 to be engaged, or the driving device 30 can drive the first locking member 11 and the second locking member 22 to be disengaged. Furthermore, by operating the driving device 30 to drive the first locking member 11 or the second locking member 22 to rotate, the user can lock or unlock the cover body 21, which can simplify the driving mechanism for locking or unlocking the cover body 21, is convenient to operate, and can improve the reliability of locking or unlocking the cover body 21, prevent the user from unlocking the cover body 21 due to accidental touching of the driving device 30, and reduce the probability of the user accidentally opening the cover.

[0063] It should be noted that the above "pot body 12" can be a pot directly containing food ingredients, or a pot for containing an inner pot, and the inner pot can be used to contain food ingredients.

[0064] Such as Figure 1 and Figure 3 As shown, according to some embodiments of the present invention, the projection of the driving device 30 in the plane of the cover assembly 20 is provided near the outer periphery of the cover body 21, that is, the driving device 30 can be located outside the cover body 21 (such as the outside shown in Figure 1 ), which is convenient for the user to operate and is beneficial to reducing the upper side of the cover body 21 (such as Figure 1The number of times of the above - side operation can reduce the probability of the high - temperature gas in the cooking appliance 100 scalding the user when the lid is opened, and improve the safety of the user operation.

[0065] As Figure 1 and Figure 2 shown, according to some embodiments of the present invention, the first locking member 11 includes a plurality of pot teeth 101, and the plurality of pot teeth 101 are circumferentially spaced apart at the top opening. The second locking member 22 includes a plurality of buckle teeth 201, and the plurality of buckle teeth 201 are circumferentially spaced apart on the lid body 21, which is convenient for the lid body 21 to be buckled with the pot body 12. That is, each of the plurality of buckle teeth 201 can pass through the gap between two adjacent pot teeth 101 to move to a position opposite to the pot teeth 101, so as to realize the snap - fit between the pot teeth 101 and the buckle teeth 201.

[0066] Among them, when the lid body 21 and the pot body 12 are in the locked state, the plurality of pot teeth 101 and the plurality of buckle teeth 201 are arranged oppositely, so that each pot tooth 101 is snap - fitted with a buckle tooth 201, which can improve the connection stability between the lid body 21 and the pot body 12, and further improve the locking effect on the lid body 21.

[0067] When the lid body 21 and the pot body 12 are in the unlocked state, the plurality of pot teeth 101 and the plurality of buckle teeth 201 are staggered, which can realize the unlocking of the lid body 21, and each of the plurality of buckle teeth 201 can pass through the gap between two adjacent pot teeth 101, so that the lid body 21 can open the top opening of the pot body 12, preventing interference between the pot teeth 101 and the buckle teeth 201, improving the smoothness of the disengagement between the lid body 21 and the pot body 12, and facilitating user operation.

[0068] As Figure 2 shown, in some examples, one end of the pot tooth 101 (such as Figure 2 the outer end shown) can be a fixed end, and the other end of the pot tooth 101 (such as Figure 2 the inner end shown) extends in the direction towards the center of the pot body 12 (such as Figure 2 the direction from outside to inside shown), and can form a free end; correspondingly, one end of the buckle tooth 201 (such as Figure 2 the inner end shown) can be a fixed end, and the other end of the buckle tooth 201 (such as Figure 2 the outer end shown) extends in the direction away from the center of the lid body 21 (such as Figure 2 the direction from inside to outside shown), and can form a free end.

[0069] Of course, one end of the pot tooth 101 (such as Figure 2 the inner end shown) can also be a fixed end, and the other end of the pot tooth 101 (such as Figure 2 the outer end shown) extends in the direction away from the center of the pot body 12 (such as Figure 2extends in the direction from the inside to the outside as shown, a free end can be formed; correspondingly, one end of the buckle tooth 201 (such as Figure 2 the outer end shown) can also be a fixed end, and the other end of the buckle tooth 201 (such as Figure 2 the inner end shown) extends in the direction towards the center of the cover body 21 (such as Figure 2 the direction from the outside to the inside shown), and a free end can be formed.

[0070] The free ends of multiple buckle teeth 201 can pass through the gaps between adjacent two pot teeth 101 to ensure that the cover body 21 and the pot body 12 can be switched between the locked state and the unlocked state. Specifically, when the first locking member 11 and the second locking member 22 rotate relative to each other, such that the free ends of the pot teeth 101 and the free ends of the buckle teeth 201 are arranged opposite to each other, the clamping fit between the pot teeth 101 and the buckle teeth 201 can be realized, and further the locking of the cover body 21 can be realized.

[0071] When the first locking member 11 and the second locking member 22 rotate relative to each other, such that the free ends of the pot teeth 101 and the free ends of the buckle teeth 201 are staggered, that is, the free ends of multiple buckle teeth 201 are arranged opposite to the gaps between adjacent two pot teeth 101, the separation fit between the pot teeth 101 and the buckle teeth 201 can be realized, and further the separation of the cover body 21 and the pot body 12 can be realized.

[0072] As Figure 1 、 Figure 3 and Figure 4 shown, in some examples, the driving device 30 includes: a driving member 33 and a transmission assembly.

[0073] The transmission assembly includes a first transmission member 31 and a second transmission member 32. The second transmission member 32 is in transmission connection with the first transmission member 31. The driving member 33 is connected to the first transmission member 31. The driving member 33 can drive the first transmission member 31 to rotate, and when the first transmission member 31 rotates, it can drive the second transmission member 32 to move, so that the first locking member 11 or the second locking member 22 can be driven to rotate by the second transmission member 32, so that the pot body 12 and the cover body 21 can be switched between the locked state and the unlocked state, and further the locking or unlocking of the cover body 21 can be realized.

[0074] By providing the first transmission member 31 connected to the driving member 33, the second transmission member 32 connected to the first locking member 11 or the second locking member 22, and making the first transmission member 31 and the second transmission member 32 in transmission connection, when the user operates the driving member 33, the first locking member 11 or the second locking member 22 can be driven to rotate to realize the locking or unlocking of the cover body 21, which can simplify the driving mechanism for locking or unlocking the cover body 21, improve the reliability of locking or unlocking the cover body 21, and is convenient for operation.

[0075] Among them, the projection of the driving member 33 on the plane where the cover assembly 20 is located is located on the outer periphery of the cover 21, that is, the driving member 33 can be located outside the cover 21 (such as Figure 1 the outside shown), which is convenient for users to operate, and is conducive to reducing the number of operations of the user on the upper side of the cover 21 (such as Figure 1 the upper side shown). It can reduce the probability that the high-temperature gas in the cooking appliance 100 scalds the user when the cover is opened, and improve the safety of user operation.

[0076] It can be understood that if the first locking member 11 is arranged on the pot body 12 and the second locking member 22 is arranged on the cover 21, the second transmission member 32 can be arranged on the pot body 12 or the cover 21, so that the driving member 33 can drive the pot body 12 or the cover 21 to rotate through the second transmission member 32, so as to drive the first locking member 11 or the second locking member 22 to rotate. Furthermore, on the basis that the driving member 33 can drive the first locking member 11 and the second locking member 22 to rotate relatively, the locking member can be integrally formed with the cover 21 or the pot body 12, which can simplify the structure, facilitate assembly, and improve the reliability of locking or unlocking the cover 21 at the same time.

[0077] If the first locking member 11 or the second locking member 22 forms a separate component, for example, the first locking member 11 is located between the cover 21 and the pot body 12 and the second locking member 22 is arranged on the cover 21, the second transmission member 32 can be arranged on the second locking member 22, so that the driving member 33 can directly drive the second locking member 22 to rotate, which can improve the stability of locking or unlocking the cover 21 and is convenient for users to operate; of course, the second transmission member 32 can also be arranged on the cover 21.

[0078] As Figure 4 shown, in some examples, the first locking member 11 is fixedly connected to the pot body 12, the second locking member 22 is fixedly connected to the cover 21, and the second transmission member 32 can be arranged on the pot body 12.

[0079] When the driving member 33 drives the first transmission member 31 to rotate, the second transmission member 32 can drive the pot body 12 to rotate relative to the cover 21, so as to drive the first locking member 11 to rotate, so that the first locking member 11 and the second locking member 22 are clamped and matched, and then the cover 21 can be locked, preventing the cover 21 from being disengaged from the pot body 12 during the operation of the cooking appliance 100, and improving the working effect of the cooking appliance 100.

[0080] On the basis of the snap - fit cooperation between the first locking member 11 and the second locking member 22, when the driving member 33 continues to drive the first transmission member 31 to rotate or drives the first transmission member 31 to rotate in the reverse direction, the first transmission member 32 can drive the pot body 12 and the first locking member 11 to continue to rotate or rotate in the reverse direction. The rotation of the first locking member 11 can cause the first locking member 11 and the second locking member 22 to disengage, thereby unlocking the cover body 21 to facilitate opening the cover body 21.

[0081] Of course, the second transmission member 32 can also be arranged on the cover body 21. When the driving member 33 drives the first transmission member 31 to rotate, the second transmission member 32 can drive the cover body 21 to rotate relative to the pot body 12 to drive the first locking member 11 to rotate, so that the first locking member 11 and the second locking member 22 are snap - fit, thereby locking the cover body 21.

[0082] On the basis of the snap - fit cooperation between the first locking member 11 and the second locking member 22, when the driving member 33 continues to drive the first transmission member 31 to rotate or drives the first transmission member 31 to rotate in the reverse direction, the first transmission member 32 can drive the pot body 12 and the first locking member 11 to continue to rotate or rotate in the reverse direction. The rotation of the first locking member 11 can cause the first locking member 11 and the second locking member 22 to disengage, thereby unlocking the cover body 21 to facilitate opening the cover body 21.

[0083] As Figure 1 and Figure 2 shown, in some examples, the first transmission member 31 is arranged on the cover assembly 20 and the first transmission member 31 can rotate relative to the cover assembly 20. The second transmission member 32 is fixedly connected to the pot body 12 and the second transmission member 32 is in transmission connection with the first transmission member 31. Thus, the rotation of the first transmission member 31 can drive the second transmission member 32 to move, so as to drive the pot body 12 to rotate relative to the cover body 21 through the second transmission member 32. Thereby, the first locking member 11 on the pot body 12 rotates relative to the second locking member 22 on the cover body 21, so that the first locking member 11 and the second locking member 22 are snap - fit to lock the cover body 21.

[0084] Furthermore, when the first transmission member 31 continues to rotate or rotate in the reverse direction, it can drive the first locking member 11 to rotate successively through the second transmission member 32 and the pot body 12, so that the first locking member 11 and the second locking member 22 are disengaged, thereby unlocking the cover body 21.

[0085] In this example, the first transmission member 31 can move along with the cover assembly 20. Thus, every time the user opens the cover of the cooking appliance 100, the first transmission member 31 is disengaged from the second transmission member 32. Based on the fact that every time the user closes the cover of the cooking appliance 100, the first transmission member 31 can be in transmission cooperation with the second transmission member 32, there is no need to additionally provide a carrier member to separately carry the first transmission member 31, which can simplify the structure of the cooking appliance 100, thereby improving the reliability of the cooking appliance 100 in use, reducing the processing cost at the same time, and facilitating assembly.

[0086] As Figure 3 and Figure 4 shown, in some other examples, the pot body assembly 10 further includes: a housing 13, the pot body 12 is disposed within the housing 13, and the pot body 12 is rotatable relative to the housing 13.

[0087] The first transmission member 31 is disposed on the housing 13, and the first transmission member 31 is rotatable relative to the housing 13. The second transmission member 32 is fixedly connected to the pot body 12, and the second transmission member 32 is in transmission connection with the first transmission member 31. Thus, the rotation of the first transmission member 31 can drive the second transmission member 32 to move, so as to drive the pot body 12 to rotate relative to the housing 13 through the second transmission member 32. At the same time, the pot body 12 rotates relative to the cover body 21, so that the first locking member 11 on the pot body 12 rotates relative to the second locking member 22 on the cover body 21, so that the first locking member 11 and the second locking member 22 are engaged, and the cover body 21 can be locked.

[0088] Further, when the first transmission member 31 continues to rotate or rotates in the reverse direction, it can drive the first locking member 11 to rotate through the second transmission member 32 and the pot body 12 in sequence, so that the first locking member 11 and the second locking member 22 are disengaged, and thus the unlocking of the cover body 21 can be realized.

[0089] In this example, the first transmission member 31 can be separated from the cover assembly 20, that is, after the cover assembly 20 and the pot body assembly 10 are disengaged, the first transmission member 31 is always in transmission cooperation with the second transmission member 32. Thus, there is no need for the user to realign the positions of the first transmission member 31 and the second transmission member 32 every time the cover of the cooking appliance 100 is closed, which is convenient for operation and can improve the user experience.

[0090] Regarding the cooking appliance 100 mentioned in the present application, in the existing operation mode, the user generally places water, food, etc. into the pot body 12, and then rotates and fastens the cover body 21 to the pot body 12. However, in the present application, the pot body 12 can rotate relative to the cover body 21 to realize the locking of the cover body 21. Compared with the prior art solution, the position of the food in the pot body 12 can be redistributed, that is, it is beneficial to evenly distribute the food inside the pot body 12 and improve the working effect of the cooking appliance 100.

[0091] As Figures 5 - 7 shown, in some other examples, the first transmission member 31 is disposed on the pot body assembly 10, and the first transmission member 31 is rotatable relative to the pot body assembly 10. The second transmission member 32 is fixedly connected to the lid body 21, and the second transmission member 32 is in transmission connection with the first transmission member 31. Thus, the rotation of the first transmission member 31 can drive the second transmission member 32 to move, so as to drive the lid body 21 to rotate relative to the pot body 12 through the second transmission member 32, whereby the second locking member 22 on the lid body 21 rotates relative to the first locking member 11 on the pot body 12, so that the first locking member 11 and the second locking member 22 are snap-fitted to lock the lid body 21.

[0092] Furthermore, when the first transmission member 31 continues to rotate or rotates in the reverse direction, it can drive the second locking member 22 to rotate successively through the second transmission member 32 and the lid body 21, so that the first locking member 11 and the second locking member 22 are disengaged, and thus the unlocking of the lid body 21 can be realized.

[0093] In this example, the first transmission member 31 is disposed on the pot body assembly 10. Thus, every time the user opens the lid of the cooking appliance 100, the first transmission member 31 is disengaged from the second transmission member 32. Based on the fact that every time the user closes the lid of the cooking appliance 100, the first transmission member 31 can be in transmission cooperation with the second transmission member 32, there is no need to additionally provide a carrier member to separately carry the first transmission member 31, which can simplify the structure of the cooking appliance 100, improve the reliability of the use of the cooking appliance 100, reduce the processing cost, and facilitate assembly.

[0094] As Figures 8 - 10 shown, in still some other examples, the lid body assembly 20 further includes: a fixed lid 23, the lid body 21 is disposed in the fixed lid 23, and the lid body 21 is rotatable relative to the fixed lid 23.

[0095] The first transmission member 31 is disposed on the fixed lid 23, and the first transmission member 31 is rotatable relative to the fixed lid 23. The second transmission member 32 is fixedly connected to the lid body 21, and the second transmission member 32 is in transmission connection with the first transmission member 31. Thus, the rotation of the first transmission member 31 can drive the second transmission member 32 to move, so as to drive the lid body 21 to rotate relative to the fixed lid 23 through the second transmission member 32, and at the same time the lid body 21 rotates relative to the pot body 12, whereby the second locking member 22 on the lid body 21 rotates relative to the first locking member 11 on the pot body 12, so that the first locking member 11 and the second locking member 22 are snap-fitted to lock the lid body 21.

[0096] Further, when the first transmission member 31 continues to rotate or rotates in the reverse direction, it can drive the second locking member 22 to rotate successively through the second transmission member 32 and the pot body 12, so that the first locking member 11 and the second locking member 22 are disengaged from each other, and thus the unlocking of the lid body 21 can be realized.

[0097] In this example, the first transmission member 31 can move together with the lid assembly 20, that is, the first transmission member 31 can be separated from the pot body assembly 10 together with the lid assembly 20. That is, after the lid assembly 20 and the pot body assembly 10 are separated, the first transmission member 31 is always in transmission cooperation with the second transmission member 32. Therefore, when the user closes the lid of the cooking appliance 100 each time, there is no need to realign the positions of the first transmission member 31 and the second transmission member 32, which is convenient for operation and can improve the user experience.

[0098] It should be noted that regarding the cooking appliance 100 mentioned in the present application, in the existing technology, the mass of the pot body 12 is generally greater than that of the lid body 21. However, in the present application, the lid body 21 can rotate relative to the pot body 12 to realize the locking of the lid body 21, which can improve the smoothness of the user operation and is convenient for various special groups (such as children or the elderly, etc.) to operate, thus improving the user experience.

[0099] As Figures 11 - 13 shown, in some examples, the first locking member 11 is arranged on the pot body 12, and the first locking member 11 can rotate relative to the pot body 12. The second locking member 22 is fixedly connected to the lid body 21. The second transmission member 32 is connected to the first locking member 11 and is in transmission connection with the first transmission member 31. Therefore, when the first transmission member 31 rotates, it can drive the second transmission member 32 to move, so as to drive the first locking member 11 to rotate relative to the pot body 12 through the second transmission member 32. At the same time, the first locking member 11 rotates relative to the lid body 21, so that the first locking member 11 rotates relative to the second locking member 22 on the lid body 21, so that the first locking member 11 and the second locking member 22 are snap-fitted to realize the locking of the lid body 21.

[0100] Further, when the first transmission member 31 continues to rotate or rotates in the reverse direction, it can drive the first locking member 11 to rotate through the second transmission member 32, so that the first locking member 11 and the second locking member 22 are disengaged from each other, and thus the unlocking of the lid body 21 can be realized.

[0101] In this example, the first transmission member 31 can be arranged on the pot body assembly 10, or the first transmission member 31 can also be arranged on the lid assembly 20. That is, the first transmission member 31 can be assembled to the pot body assembly 10 or the lid assembly 20 to drive the second transmission member 32 on the first locking member 11 to move, which can simplify the structure of the cooking appliance 100 and thus improve the reliability of the use of the cooking appliance 100.

[0102] Of course, the first locking member 11 may have a fixed seat located on the outer side of the first locking member 11 and fixedly connected to a fixing member within the pot body assembly 10. The first transmission member 31 is rotatably disposed on the fixed seat of the first locking member 11 and is always in transmission connection with the second transmission member 32 of the first locking member 11. Thus, when the user closes the lid of the cooking appliance 100 each time, there is no need to realign the positions of the first transmission member 31 and the second transmission member 32, which is convenient for operation and can improve the user experience.

[0103] In some examples, the top of the pot body 12 has a first annular flange 121, and the first locking member 11 is rotatably connected to the pot body 12 through the first annular flange 121.

[0104] The first locking member 11 further includes: a first connection ring 111. A plurality of pot teeth 101 and the second transmission member 32 are both disposed on the first connection ring 111. The first connection ring 111 is disposed on the pot body 12 and cooperates with the first annular flange 121, that is, the first connection ring 111 can be sleeved on the outer edge of the first annular flange 121 so that the first connection ring 111 can rotate relative to the pot body 12, and further the first locking member 11 can rotate relative to the pot body 12.

[0105] In some examples, the first connection ring 111 includes: a first ring body 1111 and a first limiting portion. The first limiting portion is connected to the first ring body 1111 and is located below the first annular flange 121. A plurality of pot teeth 101 are located above the first annular flange 121. Thus, the first limiting portion and the pot teeth 101 cooperate to limit the pot body 12.

[0106] In some examples, the first limiting portion includes a plurality of bottom plates 1112. The plurality of bottom plates 1112 are connected to the first ring body 1111. The first ring body 1111 and the first annular flange 121 are sleeved and arranged. The plurality of bottom plates 1112 are located below the first annular flange 121, and a plurality of pot teeth 101 are located above the first annular flange 121. Further, the pot teeth 101 and the bottom plates 1112 cooperate with each other so that the first connection ring 111 can limit the pot body 12 in its axial direction (such as the up and down direction shown in Figure 11 ), and at the same time, the first ring body 1111 of the first connection ring 111 can limit the pot body 12 in its radial direction (such as the inner and outer direction shown in Figure 11 ), which can prevent the first locking member 11 from disengaging from the pot body 12 and improve the reliability of the connection between the first locking member 11 and the pot body 12.

[0107] A plurality of bottom plates 1112 are circumferentially arranged at intervals on the first ring body 1111, and the bottom plates 1112 are arranged opposite to or staggered from the pot teeth 101, which is beneficial to the uniform force application when the plurality of bottom plates 1112 and the first annular flanging 121 rotate relative to each other, can improve the connection stability between the first locking member 11 and the pot body 12, and can also improve the smoothness of the relative rotation between the first locking member 11 and the pot body 12, thereby improving the user experience.

[0108] It can be understood that the plurality of bottom plates 1112 are connected to form an annular bottom plate 1112, which can increase the contact area between the bottom plate 1112 and the first annular flanging 121, and further improve the axial limiting effect on the pot body 12, and can also increase the force-bearing area of the bottom plate 1112 and the first annular flanging 121 to further share the acting force between the bottom plate 1112 and the first annular flanging 121, thereby improving the connection stability between the first locking member 11 and the pot body 12.

[0109] As Figure 14 and Figure 15 shown, in some other examples, the second locking member 22 is arranged on the cover body 21, and the second locking member 22 can rotate relative to the cover body 21. The second locking member 22 is fixedly connected to the cover body 21. The second transmission member 32 is connected to the second locking member 22, and the second transmission member 32 is in transmission connection with the first transmission member 31. Therefore, when the first transmission member 31 rotates, it can drive the second transmission member 32 to move, so as to drive the second locking member 22 to rotate relative to the cover body 21 through the second transmission member 32. At the same time, the second locking member 22 rotates relative to the pot body 12, so that the second locking member 22 rotates relative to the first locking member 11 on the pot body 12, so that the first locking member 11 and the second locking member 22 are engaged and matched, and the locking of the cover body 21 can be realized.

[0110] Furthermore, when the first transmission member 31 continues to rotate or rotates in the reverse direction, it can drive the second locking member 22 to rotate through the second transmission member 32, so that the first locking member 11 and the second locking member 22 are disengaged, and thus the unlocking of the cover body 21 can be realized.

[0111] In this example, the first transmission member 31 can be arranged on the pot body assembly 10, or the first transmission member 31 can also be arranged on the cover body assembly 20, that is, the first transmission member 31 can be assembled to the pot body assembly 10 or the cover body assembly 20 to drive the second transmission member 32 on the second locking member 22 to move, which can simplify the structure of the cooking appliance 100, and further improve the reliability of the use of the cooking appliance 100.

[0112] Of course, the second locking member 22 may have a fixing base located on the outer side of the second locking member 22 and fixedly connected to a fixing member within the pot body assembly 10. The first transmission member 31 is rotatably disposed on the fixing base of the second locking member 22 and is always in transmission connection with the second transmission member 32 of the second locking member 22. Thus, when the user closes the lid of the cooking appliance 100 each time, there is no need to realign the positions of the first transmission member 31 and the second transmission member 32, which is convenient for operation and can improve the user experience.

[0113] In some other examples, the edge of the lid body 21 has a second annular flange 211, and the second locking member 22 is rotatably connected to the lid body 21 through the second annular flange 211.

[0114] The second locking member 22 further includes: a second connecting ring 221. A plurality of locking teeth 201 and the second transmission member 32 are both disposed on the second connecting ring 221. The second connecting ring 221 is disposed on the lid body 21 and cooperates with the second annular flange 211, that is, the second connecting ring 221 can be sleeved on the outer edge of the second annular flange 211 so that the second connecting ring 221 can rotate relative to the lid body 21, and thus the second locking member 22 can rotate relative to the lid body 21.

[0115] In some other examples, the second connecting ring 221 includes: a second ring body 2211 and a second limiting portion. The second limiting portion is connected to the second ring body 2211 and is located above the second annular flange 211, and a plurality of locking teeth 201 are located below the second annular flange 211. Thus, the second limiting portion and the locking teeth 201 cooperate to achieve the limitation of the lid body 21.

[0116] In some examples, the second limiting portion includes a plurality of top plates 2212. The plurality of top plates 2212 are connected to the second ring body 2211. The second ring body 2211 is sleeved and arranged with the second annular flange 211. The plurality of top plates 2212 are located above the second annular flange 211, and a plurality of locking teeth 201 are located below the second annular flange 211. Further, the locking teeth 201 and the top plates 2212 cooperate with each other so that the second connecting ring 221 can limit the lid body 21 in its axial direction (such as Figure 15 the up and down direction shown), and at the same time, the second ring body 2211 of the second connecting ring 221 can limit the lid body 21 in its radial direction (such as Figure 15 the inside and outside direction shown), which can prevent the second locking member 22 from detaching from the lid body 21 and improve the connection reliability between the second locking member 22 and the lid body 21.

[0117] A plurality of top plates 2212 are circumferentially arranged at intervals on the second ring body 2211, and the top plates 2212 are arranged opposite to or staggered from the detent teeth 201, which is beneficial to the uniform force application of the plurality of top plates 2212 and the second annular flange 211 during relative rotation, can improve the connection stability between the second locking member 22 and the cover body 21, and can improve the smoothness of the relative rotation between the second locking member 22 and the cover body 21, thus enhancing the user experience.

[0118] It can be understood that the plurality of top plates 2212 are connected to form an annular top plate 2212, which can increase the contact area between the top plate 2212 and the second annular flange 211, and further improve the axial limiting effect on the cover body 21. Moreover, it can increase the force-bearing area of the top plate 2212 and the second annular flange 211 to further share the acting force between the top plate 2212 and the second annular flange 211, thereby improving the connection stability between the second locking member 22 and the cover body 21.

[0119] In some examples, the first transmission member 31 can be arranged on the cover body assembly 20, or the first transmission member 31 can also be arranged on the pot body assembly 10, and the first transmission member 31 can rotate relative to the cover body assembly 20 or the pot body assembly 10. Based on the transmission connection between the first transmission member 31 and the second transmission member 32, by rotating the first transmission member 31 itself, the switching between the locked state and the unlocked state of the pot body 12 and the cover body 21 can be controlled, which can reduce the occupied space of the first transmission member 31 in the cooking appliance 100 and prevent the first transmission member 31 from protruding too much from the surface of the cooking appliance 100, thus enhancing the aesthetic appearance of the surface of the cooking appliance 100.

[0120] In some examples, the transmission assembly includes a gear-rack mechanism, that is, the rack can be fixedly connected to the pot body assembly 10 or the cover body assembly 20 and form an arc structure. The rack meshes with the gear. By controlling the driving member 33, the gear can be driven to rotate, so as to drive the rack to move, thereby realizing the relative rotation of the first locking member 11 and the second locking member 22.

[0121] In some examples, the driving member 33 can be a manual driving member, that is, the user manually operates the driving member 33 to control the switching between the locked state and the unlocked state of the pot body 12 and the cover body 21, which can improve the reliability of locking or unlocking the cover body 21; or, the driving member 33 can be an electric driving member, that is, a driving motor can be arranged outside the driving member 33, and the output shaft of the driving motor is connected to the driving member 33. Then, the driving motor can be powered on to operate the driving member 33, and further the driving member 33 controls the switching between the locked state and the unlocked state of the pot body 12 and the cover body 21, which is convenient for operation.

[0122] In addition, the driving member 33 itself can be a driving motor, and the output shaft of the driving motor is connected to the first transmission member 31 to directly drive the first transmission member 31 to rotate, which can simplify the driving mechanism and improve the operation reliability.

[0123] As Figure 3 shown, in some examples, the lid assembly 20 can be detachably arranged on the top of the pot body assembly 10, which can prevent dirt from accumulating at the connection between the lid assembly 20 and the pot body assembly 10, and is convenient for cleaning the cooking appliance 100. At the same time, it can reduce the probability that the lid assembly 20 blocks the top opening of the pot body 12, and is convenient for the user to pour water or food into the pot body 12.

[0124] As Figure 9 shown, in some examples, the lid assembly 20 can be pivotally arranged on the top of the pot body assembly 10. Then, after the user opens the lid of the cooking appliance 100, the lid assembly 20 can still be connected to the pot body assembly 10. Based on the fact that the lid assembly 20 does not block the top opening of the pot body 12, it is beneficial to reduce the floor space of the cooking appliance 100, and when the user presses down the lid assembly 20, the lid 21 can be buckled with the pot body 12, which is convenient for the user to operate.

[0125] In some examples, the driving member 33 can be a knob, and a rotating shaft can be arranged at one end of the knob (such as Figure 9 the lower end shown). The first transmission member 31 can be a gear, and the center of the gear is fixedly connected to the rotating shaft. Then, when the user rotates the knob, the gear can be driven to rotate around the rotating shaft; the second transmission member 32 can be a plurality of teeth arranged at intervals, and the gear meshes with the teeth, so as to realize the transmission connection between the first transmission member 31 and the second transmission member 32.

[0126] It can be understood that the first transmission member 31 can also be a plurality of teeth, which are formed on the lower edge of the knob, and the plurality of teeth are arranged at intervals along the lower edge of the knob. Then, the two parts of the teeth mesh with each other, so as to realize the transmission connection between the first transmission member 31 and the second transmission member 32; that is to say, the first transmission member 31 and the knob can be integrally formed.

[0127] As Figure 3 and Figure 4 shown, according to some specific embodiments of the present invention, the cooking appliance 100 includes: a pot body assembly 10, a lid assembly 20 and a driving device 30.

[0128] The pot body assembly 10 includes a pot body 12, an outer shell 13, and a first locking member 11. The pot body 12 has an opening at the top. The pot body 12 is disposed inside the outer shell 13, and the pot body 12 is rotatable relative to the outer shell 13. The first locking member 11 is disposed on the pot body 12 and is arranged around the top opening of the pot body 12. The cover body assembly 20 is pivotally disposed on the top of the pot body assembly 10. The cover body assembly 20 includes a cover body 21 and a second locking member 22. The second locking member 22 is disposed on the cover body 21 and is arranged around the cover body 21.

[0129] The driving device 30 includes a driving member 33 and a transmission assembly. The transmission assembly includes a first transmission member 31 and a second transmission member 32. The driving member 33 and the first transmission member 31 are rotatably disposed on the outer shell 13. The driving member 33 is connected to the first transmission member 31. The first transmission member 31 is in transmission connection with the second transmission member 32, and the second transmission member 32 is fixedly connected to the pot body 12.

[0130] When the user operates the driving member 33, the first transmission member 31 can be driven to rotate. The rotation of the first transmission member 31 can drive the second transmission member 32 to move, so as to drive the pot body 12 to rotate through the second transmission member 32. The rotation of the pot body 12 can drive the first locking member 11 to rotate relative to the second locking member 22 on the cover body 21, so that the first locking member 11 and the second locking member 22 are engaged and matched, and the locking of the cover body 21 can be realized.

[0131] Then, the user can operate the driving member 33 to drive the first transmission member 31 to rotate further, so that the first locking member 11 rotates further relative to the second locking member 22, and the first locking member 11 and the second locking member 22 can be disengaged, and the unlocking of the cover body 21 can be realized.

[0132] The other components and operations of the cooking appliance 100 according to the embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail here. In the description of the present invention, the "first feature" and the "second feature" may include one or more of such features.
